Cuíca (Portuguese pronunciation: [kuˈikɐ]), or "kuweeca", is a Brazilian friction drum with a large pitch range, produced by changing tension on the head of the drum. Cuíca is Portuguese for a type of small opossum which is known to make a high-pitched sound. It is most often used in samba music. The tone it produces has a high-pitched squeaky timbre. It has been called a 'laughing gourd' due to this sound. Many also claim that the cuica has a "monkey" sound.
